Super baggy
Fit Type: 7" Inseam, Size: X-Large, Color: Dusty Blue
Light weight and nice thin material. These things are super baggy and make you look funny. I wouldn’t wear them in public.

Great shorts.
Fit Type: 7" Inseam, Size: Large, Color: Dark Grey
Great shorts for working out in. They’re nice and light and I like how the pockets have zippers. I purchased blue ones first and I liked them so much. I ordered the gray ones.

Look great and feel wonderful for the gym.
Fit Type: 7" Inseam, Size: XX-Large, Color: Grey Camo
My favorite gym shorts. Not a ton of pockets, but the front pockets zip closed and fit my phone and headphones well. They dry very fast, look great, and are light enough and comfortable enough to work out in.

Great feel and color
Size: Medium, Color: Ocean Depths, Size: Medium, Color: Ocean Depths
Absolutely love this tank top! The color is gorgeous and exactly like the pictures — super vibrant and flattering. The ribbed material feels soft but still has enough stretch to hug in all the right places. I also really like the built-in padding and racerback style because it makes it easy to wear without needing extra layers. The only thing I would mention is that it runs a little small, especially if you want a more relaxed fit. I’d recommend sizing up if you’re between sizes. Other than that, it’s a great basic top that looks cute dressed up or casual!

Vibrant Racer Back Tank !!!
Size: X-Small, Color: Hot Pink, Size: X-Small, Color: Hot Pink
I purchased this Danysu V Neck Racer Back Tank Top for Women Padded Ribbed Long Tank Fitted Basic Cami Tops to wear under my off-shoulder top for an upcoming 80’s dance party, and it works perfectly for what I needed! The bright pink color really pops and adds the perfect retro accent to my outfit. I intentionally ordered the XS because I did not want it to fit loose under my top, and it definitely gives a snug, fitted look. The ribbed material is soft and stretchy, and the built-in padding is a nice bonus. I would recommend sizing up if you plan to wear it alone or if you are curvier, as the XS runs very tight. However, for layering under another top as I did, it worked out exactly the way I wanted. Super cute, flattering, and great for layering or workouts!
